BATTERY HAND LAMP.

Application filed April 30, 1927. Serial No. 187,771.

This invention relates to battery hand lamps of the type including a casing for the battery, a lamp bulb with a suitable reflector in one end of the casing and an end glass or lens for enclosing and protecting the bulb and reflector. The present invention relates more particularly to means for retaining,

supporting and centering the end glass or lens in the end of the hand lamp over the reflector and lamp bulb.

Hand lamps of the type described are usually provided with tubular or cylindrical battery casings,'and the reflector surrounding the lamp bulb is ordinarily inserted in one end of the casing, being retained in place by a suitable flanged retaining band.

The end glass or lens is clamped between the flange of the retaining band and the end of the casing or the reflector, and thus both the lens and the reflector-are secured in place by means of this retaining band. When it is desired to replace or remove the lamp bulb or the reflector, the retaining hand must be removed from the end of the casing, and

= the end glass or lens which is normally held in place by the flange of this band is then likely to fall out and become broken. As the end glasses or lenses employed in hand lamps of the type described are usually beveled or curved on their outer surfaces, it has been found diflicult to center such glasses with respect to the retaining band, the curved outer surface permitting the glass to slip with respect to the flange on the band and so to assume a' slightly eccentric -posi-,

tion with respect to the band.

With the above and other considerations in mind, it is proposed in accordance with the present invention to provide a hand lamp having a flanged lens retaining'band embodying means for removably securing the end glass or lens therein, and, more specifically, it is proposed to provide a lens retaining ring whichreleasably cooperates with the retaining band to secure the end glass or lens thereto and to center the glass within the band.

It is a further object of the invention to provide a retaining means of the type described which is simple in construction, in

expensive and highly effective.

Other specific objects, advantages and characteristic features of the invention will together with the end glass,

detailed descripdetail, reference will be made to the accompanying drawings, in which Figure 1 is a view of the blank from which the'retaining ring of the present invention is struck;

Fig. 2 is an inner end view of retaining ring;

Fig. 4 is a side view of the retaining ring showing the relative positions of these arts;

Fig. 5 is a side view oi the flanged lens retaining band with the end glass and retaining ring in place therein;

L Fig. 6 is a sectional view, taken'along the hue 6-6 of Fig. 5, and viewed in the direction'of the arrows; and Y V Fig. 7 is a side view, partly in section, or a portion of a hand lamp with the end glass secured thereto by the retaining means of the present invention.

Referringto the drawings, the lens retaining means of the present invention is shown in connection with a tubular or cylindrical hand lamp'having an enlarged reflector and end glass, it being understood that the invention is equally applicable to many other types of lamps. Referring to Fig. 7, the hand lamp showncomprisesa battery casing 1 having an enlarged end com part-ment 2 within which is located a reflector 3 of suitable shape, surrounding a lamp bulb 1. The casing 1 contains the usual battery or other source of energy for the lamp 1 and is preferably provided with a suitable switch for controlling the flow of current through the lamp bulb, but as these means form no part of the present invention, and are well known to those skilled in the art,

ring, taken hereinafter described. I

An end glass or lens retaining band B is provided having a cylindrical portion 7 the lens 1 which is screw threaded as shown whereby this band may be securedto the enlarged end 2 of the casingl. An inturned flange 8 is provided on the band B, this flange being preferably flared to conform with the outer beveled or curved surfacelof an end lass or lens, The band B may be formed in any suitable shape, and as shown, is provided with an octagonal edge portion 9 to facilitate removal of the band from-the casing. Any suitable type of lens or end glass may. be employed, and in the embodiment shown, an end glass 10 having plane surfaces andbeveled edges is provided.

Referring now more particularly to the end glass retaining ring R, shown in detail in Figs. 1 through 4, this ring is preferably formed of comparatively thin resilient sheet metal, and has an internal diameter sub stantially equal to the inside diameter ofthe flange 8 on the band B. The ring. R: is broken or out along 1 a radial line 11, and is provided at its outer edgewith a plurality of equally spaced end glass retaining lugs 12, extending outwardly substantially at are right anglesatothe ring R. The lugs 12 preferably formed integralwith the ring B, being struck," pressed or cut therefrom in any suitable manner; A plurality of inwar'dlyextending rounded ears 13are provided 01f the outer, edge of the ring at points, equally spaced from adjacent lugs 12, the'ears13 being preferably formed integral with theiringl R. Theyears 13.,are bentat an angle to extend outwardly from the edge of the ring R, as shown inFig. 3.-

When' it is desired to securethe end glass 10 within the band B,*the glass is first placed within the band with the bevel of the glass resting on the flared :flangeqS- as shown in-Figsjo and 7 The retaining'ringwR isa then slightly compressed and placed withinthe cylindrical portion 7 of the bandB with the-lugs 12 toward the and glass. The ring R; extends, within the octagonal portion of the band B, the lugs 12 engaging the outer edges of the glass 10 and the cars 13 resting on the ledge formedby the octagonal por tion -9, as clearly shown in Figs. 5. and I.

In" this, manner,,the glass 10,is securely,

clampfld'withinthe bandj B. The band B may-then be secured to the casing ,1, the refl'ector 3 being clamped against the flange 5-; of "the casing by the: engagement ofthe ring R with'the outer surface of the; flange 6 Thelugs 12 serve to center the end glass win the band B, while the cars 13 securely clamp the glass in engagement with ,the flange 8 on the band.- Due to thebreak 11 inthering-R, this ring is readily adaptable to slight variations in the diameters of the lenses or end glasses employed, the ring heing feasily'expansible toaccommodate lenses having diameters larger than the diameter defined by the lugs 12 when the ring is in Y the contracted condition as shown in Fig. 2.
